SystemStats::is64Bit would be handy. It’s useful if you’re doing things like running 32-bit code on a 64-bit OS.

Here’s a Windows version:

[code]#ifdef \_WIN64

bool SystemStats::is64Bit()  
{  
return true;  
}

#else

typedef BOOL (WINAPI \*LPFN\_ISWOW64PROCESS) (HANDLE, PBOOL);

bool SystemStats::is64Bit()  
{  
LPFN\_ISWOW64PROCESS  
fnIsWow64Process = (LPFN\_ISWOW64PROCESS)GetProcAddress(GetModuleHandle(“kernel32”),“IsWow64Process”);

BOOL bIsWow64 = FALSE;

```
if (NULL != fnIsWow64Process)
{
fnIsWow64Process(GetCurrentProcess(),&bIsWow64);
}

return FALSE != bIsWow64; // convert from BOOL to bool

```

}

#endif

[/code]

Ok, thanks Matt, I’ll maybe pop that in there.
